When Prior Auth Parity Is Only Verifiable on Paper
Across six Medicaid managed care organizations in New York and Kansas, every written prior authorization policy reviewed by OIG met parity requirements. The records needed to establish what happened in practice told a much less complete story.

The Prior Auth Operating View Framework
A new way to measure the work behind prior authorization
Approval and denial rates tell only part of the story. The Prior Auth Operating View Framework introduces three dimensions for examining the administrative work behind authorization: Authorization Workload, Failure Origin, and Resolution Burden.

What is prior authorization?
Prior authorization is a requirement that clinicians obtain approval from an insurer before certain treatments, procedures, or medications are provided. The insurer reviews the request against applicable criteria and issues a determination. The Prior Auth Index tracks public reporting related to this process, including approval rates, denial rates, decision timelines, appeal outcomes, and source availability.
Purpose and scope

Prior authorization reporting is now subject to public disclosure requirements under CMS-0057-F. Publication status alone does not establish usability, comparability, or completeness.

Plans report in different formats, at different URLs, with inconsistent definitions and varying levels of granularity. The result is a fragmented public dataset that requires source mapping, normalization, and review before it can be interpreted across plans.

The Prior Auth Index brings together source-linked payer reporting, independent analysis, and operational research to examine what published metrics reveal, where reporting falls short, and what additional visibility is needed to understand authorization performance.

Who this is for

The Prior Auth Index serves professionals and organizations seeking a clearer understanding of payer-reported performance, administrative burden, and the operational challenges surrounding prior authorization:

  • Revenue cycle and utilization management teams tracking payer reporting patterns and operational shifts
  • Consultants and analysts researching prior authorization trends across markets
  • Healthtech operators evaluating payer infrastructure and emerging vendor patterns
  • Payer strategy and contracting teams reviewing plan-level metrics and regulatory movement
  • Journalists and researchers studying prior authorization patterns
  • Anyone who wants the monthly analysis without digging through the raw filings themselves
